Cartoon background music matching method based on convolutional neural network recognition

The invention discloses a cartoon background music matching method based on convolutional neural network recognition. The method comprises the following steps: step 1, acquiring a music playing instruction and a currently read cartoon page; 2, carrying out the image recognition of the cartoon through a preset CNN model, and obtaining a style label and a scene label of the cartoon; 3, text content information and main language types in the cartoon are extracted through the OCR technology; 4, performing NLP text analysis on the text content information to obtain a theme tag; 5, according to style labels, scene labels, language types and theme labels of all the cartoons in the current reading page, matching music in a music library after average weighting calculation; and step 6, playing the matched music. According to the method, information such as the style of the cartoon is recognized through the convolutional neural network model, the music of the corresponding type is selected for playing, the reading inte
